changing color of pedal line segments

[Kieran Coulter]

Hello,

My last email didn't seem to get sent properly, so I'm retrying.

I have a question as to whether or not I can change the
colour of the bracket style pedal line. I have achieved the bracket
style pedal line successfully placing " \set Staff.pedalSustainStyle =
#'bracket " inside of the _expression_, but in my attempt to construct a
tweak to change the colour of the pedal line to a noticeable red (I
wish to draw the attention of my student towards the pedal line), I am
not successful. By best attempt at the tweak is :

" \override Staff.pedal #'color = #red "

but it doesn't seem to work. I hope to be able to colour the 

" \sustainUp "
" \sustainDown " and
"
\sustainUp\sustainDown " segments individually, so that I can draw
attention to the particular pedal motion my student happens to miss.

Hopefully this is possible! Thanks very much.
